Looking for Charles Eggleston of Long Island, NY

They are the sons of Oswald* and Katherine (not sure of the correct spelling) Eggleston. *(Oswald is the nephew of Ida Eggleston of Hammondsport, NY. She was born on April 9, 1875 to David and Catherine Eggleston. She passed away on November 28, 1938 in Rochester, NY.)

Charles was born in Long Island, NY and was raised in Rochester, NY. He will be about 70 now. Robert and Gary were probably born in Rochester. If anyone can help me find any of them it would be greatly appreciated. Thank you for taking the time to read this.
